My local pet store got in some snakes they had no clue about and thought were garters. I identified a couple of ribbons for them, but there was 1 snake that was solid green like a tree boa, but the size and shape of a ribbon. I didn't think much about it but they told my wife when she was in for feeders that the snake wasn't eating fish or crickets and if we thought we could save it we could have it. I don't really want another ribbon, but I'd like to save the snake, and I figure the first step is ID. Any ideas?

I'll try to stop by and get some photos if I can.
